Counterweight lift cylinder seal kit for Demag AC615

The 77160973 seal kit provides the components required to restore the sealing function of the counterweight lift cylinders. These cylinders are responsible for positioning and securing the counterweight system, which is critical for maintaining the stability of the crane during lifting operations. By replacing worn seals, the kit helps prevent hydraulic fluid leaks and protects the internal cylinder components from external contaminants.

This kit is specifically engineered for use in the Demag AC615 all-terrain crane. It is designed to match the requirements of the hydraulic cylinders that manage the counterweight assembly, ensuring that the system can maintain the necessary pressure and position under load.

A hydraulic cylinder seal kit typically includes a variety of components such as O-rings, piston seals, rod seals, backup rings, and wipers. These elements create a barrier against internal and external fluid leakage, which is essential for the efficient operation of hydraulic systems. Over time, seals may experience wear due to friction, pressure, and temperature fluctuations, which can lead to pressure loss or cylinder drift. Regular maintenance using this kit helps preserve the operational integrity of the hydraulic system.
